Specification of Letters Patent.

Patented June a, 1918.

Application filed January 17, 1917. Serial No. 142,823.

To all whom it may concern:

Be it known that I, JOHN HARRIS, a citizen of the United States, resident of Lakewood, county of Cuyahoga,and State of Ohio, have invented new and useful Improvements in Heaters, of which the following is a specification. the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

My invention relates to heaters and particularly to that class of such devices in which hot exhaust gas, hot air or any other hot gaseous heating medium is received from such heating devices as an automobile engine, coal or gas stove, etc., and the remai ing heat in such media which in devices heretofore used has been mainly lost, is utilized.

The objects of the invention are to provide a device accomplishing this function which would be economical in cost, simply constructed and easily assembled. A further object of the invention is to actually replace by means thereof some component parts of well-known heating devices, such as utilizing my improved heater as the stove pipi e or part thereof in coal or gas stoves.

he annexed drawing and the following description set forth in detail certain means embodying my invention, the disclosed means, however, constituting but one of various mechanical forms in which the rinciple of the invention may be employed In said annexed drawing Figure 1 represents a side elevation and longitudinal section of my improved heater, as applied to an automobile, for utilizing the exhaust gases to heat the passenger compartments, said view also particularly showing the method of fastening the edges of the two casing elements in each unit of my heater; Fig. 2 represents a vertical section taken in the plane indicated by line IIII, Fig. 1; Fig. 3 represents an end elevation taken from the left side of Fi 1; and Figs. 4 and 5 are illustrations 0' the use of my device in connection with coal and gas stoves, the same illustrating further, the use of the device as the pipe or part of the pipe of said stoves.

In the annexed drawing, a heater is represented by 1 which is composed of units 2, each such unit consisting of two circular casing portions 3 and 4 united to form an inclosed casing by turning and sealing the edge of one of such casing portions over the 1 edge of the other portion. as plainly shown in Fig. 1. Each such casing portion is formed with a lateral annular collar 5 bounding an opening 6. the opening upon one side of each unit 2 being of slightly greater diameter than the opening upon the other side of the unit, whereby units 2 can be assembled. Each such unit 2 further comprises a plate 7 disposed within the easing portions 3 and 4. said plate being circular, of substantially the same diameter as the casing portions 3 and 4 and the edges of the same confined between the edges of said casing portions, so that the said plate 7 is symmetrically disposed with reference to said portions, as plainly shown in Fig. 1. By reference to said figure it will be noted that the precise means for rigidly securing the edge of the plate 7 intermediately the casing portions 3 and 4: consist in a marginal flange formed upon the casing portion 4 and secured within a recess formed by a three sided flange member formed upon the casing portion 3, the outer edge of the plate 7 being rigidly secured in said recess. Said plate 7 is formed with an annular series of perforations 8 and a small central bolt aperture 9. The opening 6 in the walls of the casing portions 3 and 4 are staggered in their relation to the perforations 8, as plainly shown in Fig. 1, so that the plate 7 and the walls of the casing portions 3 and 4 form baffling surfaces to the passage of a heating medium through an assembled heater, as shown in Fig. 1. Such assembled heater 1 is made rigid by uniting a series of units 2 in any approved manner, as by means of a bolt 10 interesecting the series 7 of apertures 9.

In the accompanying drawing, three methods of using my improved heater are illustrated. In Fig. 1, said heater is secured to the floor 11 of an automobile through the medium of the elbows 12, one of said elbows in turn being connected by means of a flexible tube 13 to the exhaust pipe (not shown) of an automobile, and the other elbow discharging into the atmosphere. In Figs. 4C and 5. a series of units 2 are assembled to form a heater 1 upon a coal stove 14 or gas stove 15 and said heater forms a part or all of the pipe of said stove. Many other uses of the device will come within the spirit of my invention.

By the improvement hereinbefore described and shown in the accompanying drawin I have provided very efficient means or utilizing all of the heat in many heating media which has heretofore been lost and this result is particularly obtained by reason of the very large heating area provided in my improved device and by means of the bafliing surfaces provided therein, in addition to the replacement thereby of some well-known parts of other heating devices such as pipes.

What I claim is In heaters, a plurality of elements each comprising a casing formed of two oppositely dis osed perforated sections providing a ra iating surface, and a perforated termediately the casing sections, the perforations of said sections and said plate being staggered relatively to each other, means providing communication between adjacent elements, and means for connecting said elements.

igned by me, this 8" day of January, 1917.

JOHN HARRIS.
